I tried a blue jeans cable to compare it to my $1000 cable and I sent the blue jeans back once it got broken in (100 hours). I’m sure it would be a step up to cheap/free cables but lifeless/dull sounding compared to better cables.
When you get an Ethernet cable, it’s not the speed that you need, it’s the better terminations that the better cables give you. Audio throughput is small, remember a cd player spins at an avg 300 rpm with small data output. A cat5e cable would be fine even up to dsd. I have a top of the line audioquest Ethernet cable
